SeaSmart Vessel Analog Gateway

This innovative compact unit directly connects up to 8 analog senders to marine networks including NMEA 0183, NMEA 2000, Ethernet, or Wi-Fi (802.11 b/g). Designed to add digital display support for single or dual engine configurations, the SeaSmart Analog Gateway converts sensor data into compatible network protocol for display on modern Chart plotters, PC/iPad devices, or any internet Web browser device.

 

A 9-pin flying lead sensor harness attaches to each vessel sensor and water-resist twist-lock connector insures reliable performance in harsh environments. Each of the 8 analog inputs can be configured for resistive or voltage sensor inputs to cover any instrumentation requirement. Two of the inputs can be enabled for pulse style for use with most tachometer signals including inductive, Hall-Effect, generator, and alternator.

The versatile Analog interface design allows the unit to be user configurable to support any analog sender via its exclusive embedded calibration tables. Unique only to SeaSmart.net is a proprietary field installable sensor module which contains selected calibrations preprogrammed in non-volatile memory. This allows the installer to select from a growing list of preconfigured vessel engine packages and simply plug in the desired module to complete unit setup without needing to connect a PC. As a result, the SeaSmart Analog Gateway will provide basic instrumentation for dual engines (Tachometer, Engine Temp, Oil Pressure, and Alternator Voltage) or more extensive Single Engine package (Fuel level, Transmission Pressure, Battery Bank status, and more.) Sensor inputs can come from any resistive sender, voltage sender or even operate in parallel with most existing analog gauges thereby allowing for a simple upgrade path on older analog engines to the new digital marine networks.

Based on the SeaSmart.net line of marine adapters, the SeaSmart Analog Gateway can be purchased with options to support popular network interfaces including NMEA 0183, NMEA 2000, Ethernet, or Wi-Fi. NMEA 0183 provides bot serial RS232 and USB output to compatible equipment or PC platforms. The NMEA 2000 option allows for direct instrument display on compatible Marine Chart plotters and automatically populates preconfigured gauges with data from older analog engine packages. The Ethernet and Wi-Fi options provide interface to on-board PC or iPad devices running a growing list of SeaSmart.net compatible applications including the popular iNavX and vDash. The Ethernet/WiFi options also allow remote access to vessel data over the internet using a built-in Web Server thus enabling a single low-cost device solution for remote monitoring anywhere in the world.
